Dual citizenship is another question from deportation, I think. Non citizens can still have legal status. As far as dual citizenship is concerned, those who have citizenship through their parentage and then citizenship through ius soli seem more likely to be reasonably deported. Those who would become de facto "stateless" should give us pause for the denial of citizenship. Obviously that would have to be judged in a more individual basis through the asylum process, presently overloaded to unbelievable proportions. I believe 17 million applications for asylum were received between 2021-2024.
